BACKGROUND

1. Technical Field

The present disclosure relates to a dual air regulated spray applicator.More particularly, the present disclosure relates to an applicatordevice having a double-barreled syringe or cartridge, removably mountedon a handle, and containing components or compositions of a tissueadhesive or sealant, e.g., glue, tissue sealant or bone cement, to bemixed by an applicator assembly of the device.

2. Background of Related Art

During various surgical procedures it is often necessary to closepuncture wounds, leaks or incisions in tissue. Typically, this is donethrough the use of sutures or staples to close the puncture wounds,leaks or incisions. Recently however, various synthetic and/or naturaladhesive or sealant substances have been developed to be applied totissue. Originally, the compositions of the adhesives or sealants weresimply mixed together and applied with an applicator device or stick.Advancements in this technology have provided devices which are capableof receiving the compositions from external sources and expelling themonto tissue to be mixed on the tissue site. These devices are oftencumbersome and bulky and provide little or no control over the amount ofpressure used to discharge the various compositions and/or compensatefor the appropriate mixture percentages.

Therefore, it may be desirable to provide a self-contained applicatordevice having a cartridge or double-barreled syringe, containing theseparate components or compositions to be mixed into an adhesive orsealant, removably mounted to a handle. It may also be desirable to havea self-contained applicator device capable of mixing the compositionswithin the device and expelling them as a single composition of anadhesive or sealant for application to tissue. It may be furtherdesirable to have an applicator device capable of varying the amounts ofpressure to each of the compositions in order to adjust for the mixturesof the components contained therein.

Further, the pressure levelprovided by third regulator 49 may be set at a second level when firstregulator 34 and second regulator 36 are turned off, or in the absenceof double-barreled syringe 18, to facilitate cleaning or clearing anyresidual components contained within atomizing tip 20 or discharge tube28.

Referring now to FIG. 2, as noted above, double-barreled syringe 18includes a first cylinder 30 and a second cylinder 32. A first plunger78 is movably mounted within first cylinder 32 and is provided to ejecta first composition out of first cylinder 32 and into atomizing tip 20.First cylinder 32 includes a first discharge tube 80 which is in fluidcommunication with atomizing tip 20. First cylinder 30 also includes afirst pressure inlet 82 for connection to distal end 40 of firstpressure line 38. Likewise, second cylinder 32 includes a second plunger84 movably mounted therein to eject a second composition into atomizingtip 20. Second cylinder 32 also includes a second discharge tube 86 influid communication with atomizing tip 20 and a second pressure inlet 88for connection to distal end 46 of second pressure line 44. As shown,first pressure inlet 82 and second pressure inlet 88 are ribbed tosecure first pressure line 38 and second pressure line 44 thereto. It isalso envisioned for at least one of first pressure inlet 82 and secondpressure inlet 88 to be threaded.

With continued reference to FIG. 2, double-barreled syringe 18 isremovably mounted within handle 16. Elongated portion 22 of handle 16 isprovided with a first channel 90 for receipt of first cylinder 30 and asecond channel 92 for receipt of second cylinder 32. A first atomizingport 94 is provided on atomizing tip 20 for receipt of first dischargetube 80. A second atomizing port 96 is provided on atomizing tip 20 forreceipt of second discharge tube 86.

To secure double-barreled syringe 18 against longitudinal motion withinhandle 16, a first circumferential projection 98 is provided on firstcylinder 30 and is engageable with a first recess 100 on handle 16.Likewise, a second circumferential projection 102 is provided on secondcylinder 30 and is engagable with a second recess 104 on handle 16.Other suitable methods may be used to secure double-barreled syringe 18within handle 16.

A third pressure inlet port 106 is provided on handle 16 for connectionto distal end 52 of third pressure line 50. Third pressure inlet port106 is in fluid communication with atomizing tip 20 in a mannerdescribed in more detail herein below.

Referring now to FIGS. 2, 3 and 4, the operation of first clip 68 andsecond clip 70 to retain double-barreled syringe 18 within elongateportion 22 of handle 16 is described. As shown, first clip 68 includes astraight portion 108 and an angled portion 110. First clip 68 ispivotally mounted to elongate portion 22 and is movable from an openposition wherein straight portion 108 is spaced from a first recess 112formed in elongate portion 22 to a closed position wherein straightportion 108 is substantially flush within first recess 112. In theclosed position, angled portion 110 secures cylinder 30 within firstchannel 90 formed in handle 16. Likewise, second clip 70 is pivotallymounted to elongate portion 22 and is movable from an open positionwherein straight portion 114 is spaced from a second recess 118 to aclosed position wherein straight portion 114 is substantially flushwithin second recess 118. In the closed position, angled portion 116secures second cylinder 32 within recess 92 formed in handle 16. Asnoted above, cylinders 30 and 32 of double-barreled syringe 18 may beprovided as a single unit or maybe provided separately.

Referring to FIGS. 5A and 5B, the operation of first plunger 78 andsecond plunger 84 is described. As shown in FIG. 5A, in an initialposition, first plunger 78 and second plunger 84 are in a proximal-mostposition within first cylinder 30 and second cylinder 32, respectively.First composition A is contained within first cylinder 30 and secondcomposition B is contained within second cylinder 32.

Referring now to FIG. 5B, as air pressure is injected into firstpressure inlet 82, in the direction of arrow C, the air pressure drivesfirst plunger 78 distally within first cylinder 30. As first plunger 78moves distally, it forces first composition A distally and out firstdischarge tube 80 in the direction of arrow E. Likewise, as air pressureis injected into second pressure inlet 88, in the direction of arrow D,the air pressure drives second plunger 84 distally within secondcylinder 32 to force second composition B out of second discharge tube86 and in the direction of arrow F. As noted above, first discharge tube80 and second discharge tube 86 are in fluid communication withatomizing tip 20. Thus, first and second compositions A and B are forcedinto atomizing tip 28 to be mixed therein.

As illustrated in FIG. 7A, it is envisioned for a portion of theatomizing tip 20 to include a static mixer 200. For instance, staticmixer 200 may be disposed at least partially within discharge tube 28and/or within an atomizing chamber 120 (discussed below). Further,static mixer 200 may include a plurality of baffles 202 or the like. Inthis embodiment, as first and second compositions A and B are forcedthrough static mixer 200, compositions A and B may be repeatedly dividedby baffles 202 and recombined, creating a substantially uniform mixture.Baffles 202 of this embodiment may remain substantially motionless asfirst and second compositions A and B pass therethrough. The mixture maythen be discharged toward a target site.

The operation of applicator device 10 to mix and atomize first andsecond components, or first and second compositions A and B, anddischarge them from applicator device 10 is described. Prior toassembling double-barreled syringe 18 with handle 16, the appropriatedouble-barreled syringe 18, having cylinders 30 and 32 containing thedesired compositions A and B is selected, depending upon the intendeduse. Referring to FIGS. 1 and 2, double-barreled syringe 18 is insertedinto handle 16 by initially positioning first discharge tube 80 withinfirst atomization port 94 and second discharge tube 86 within secondatomization port 96. First circumferential projection 98 is positionedwithin first recess 100 and second circumferential projection 102 ispositioned within second recess 104. As noted above, first and secondcylinders 30 and 32 are received within first channel 90 and secondchannel 92 formed in elongate portion 22 of handle 16. Thereafter,double-barreled syringe 18 is secured to handle 16 by pivoting firstclip 68 and second clip 70 about cylinders 30 and 32, respectively.

Referring to FIGS. 1 and 2, distal end 40 of first pressure line 38 ispositioned over first pressure inlet 82 on first cylinder 30. Likewise,distal end 46 of second pressure line 44 is positioned over secondpressure inlet 88 on second cylinder 32. Distal end 52 of third pressureline 50 is positioned over third pressure inlet 106. Applicator device10 may be provided with control cable 62 permanently affixed tocontroller 58 or may be detachable therefrom.

Referring to FIG. 7A, atomizing tip 20 includes atomizing chamber 120 influid communication with discharge tube 28. As shown, first and seconddischarge tubes 80 and 86 of cylinders 30 and 32, respectively, are influid communication with atomizing chamber 120. As noted hereinabove,third pressure inlet 106 is in fluid communication with atomization tip20 and thus with atomizing chamber 120. A pressure bore 122 extends fromthird pressure inlet 106 to atomizing chamber 120. Thus, air pressureforced through third pressure inlet 106 is directed into atomizingchamber 120 to facilitate mixing and atomization of compositions A and Bdischarged from first and second discharge tubes 80 and 86,respectively. As an alternative to atomizing chamber 120, dischargetubes 80 and 86 may be directly connected to discharge tube 28 to mixthe compositions within discharge tube 28. In this embodiment, pressurebore 122 will also be in direct fluid communication with discharge tube28 to mix the compositions therein and provide a source of discharge airpressure.

With reference to FIG. 8A, further components of actuation assembly 56are described. A contact switch 124 is positioned within pistol grip 24and is connected to control cable 62. Control cable 62 enters pistolgrip 24 and is supported within pistol grip 24 by a grommet 126. Trigger60 is pivotally mounted to elongate portion 22 at a pivot point 128.Trigger 60 is pivotable to engage and move a depressor 130 againstcontact switch 124 to actuate applicator device 10. Depressor 130 isbiased away from contact switch 124 by a spring 132.

Referring now to FIGS. 6, 7B and 8B, to actuate applicator device 10regulator flow control knobs 76, 74, and 72 are set to the appropriatelevels. Trigger 60 is depressed against the bias of spring 132 movingdepressor 130 into engagement with contact switch 124. This actuatescontroller 58 which in turn actuates first regulator 34 providing afirst source of air pressure source through pressure line 38 to firstcylinder 30 and actuates second regulator 36 which provides a secondsource of air pressure through pressure line 44 to second cylinder 32.Air pressure in cylinders 30 and 32 drives plungers 78 and 84 distallyforcing first composition A and second composition B towards theirrespective discharge tubes 80 and 86. Thus, first composition A andsecond composition B are forced into atomizing chamber 120 ofatomization tip 20.

As trigger 60 is depressed, it also actuates third regulator 49 whichcauses a flow of air pressure through pressure line 50 and pressure bore122 in elongate portion 22 and into atomizing chamber 120. As airpressure is forced into atomizing chamber 120, the air pressure mixes,or atomizes, compositions A and B together to form a single compositionA+B which is discharged out of applicator device 10 through dischargetube 28 for application to tissue or bone.

Once the operator has finished using applicator device 10 to apply besubstances, e.g., tissue adhesive or sealant, bone cement, etc., trigger60 is released, thus discontinuing actuation of the applicator device.Thereafter, clips 68 and 70 can be pivoted away from elongate portion 22to remove double-barreled syringe 18. Should further use of applicatordevice 10 be necessary, trigger 60 can again be depressed causing a flowof air from third regulator 49 into atomizing chamber 120 and dischargetube 28 to clear any residual compositions contained therein. Asubsequent double-barreled syringe 18 containing further or differentcompositions may be installed in handle 16 and the procedure repeated.

It is envisioned that atomizing tip 20 or another suitable part ofapplicator device 10 is disposable. It is further envisioned thatatomizing ports 94, 96 are disposed in a removable insert (not shown),which is insertable near distal end 26 of the elongate portion 22. Theinsert may also be disposable.

It will be understood that various modifications may be made to theembodiments disclosed herein. For example, while the disclosedapplicator device uses a double-barreled syringe for mixing twocompositions, it is also contemplated that multiple barreled syringesalong with additional regulators may be provided to mix more than twocompositions through the applicator device. Further, as noted above, asan alternative to the use of an atomizing chamber, the discharge tubesof the cylinders may be directed directly into the discharge tube of theatomization tip and the third source of air pressure directed directlyinto the discharge tube of the atomization tip to mix the compositionsdirectly within the discharge tube. Additionally, while the applicatorassembly and regulator assembly have been described as separate unitsconnected by pressure and control lines, the regulator assembly,including the controller, may be contained entirely within theapplicator assembly for a single compact unit. Still further, othersources of driving fluid or gas, such as, for example, saline, oil,etc., or combinations thereof, may be used as an alternative to or incombination with air as a source of the driving pressure. Therefore, theabove description should not be construed as limiting, but merely asexemplifications of particular embodiments. Those skilled in the artwill envision other modifications within the scope and spirit of theclaims appended hereto.
